Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

Fig. 1 depicts a net including a driver circuit and a receiver circuit interconnected by an unterminated length of transmission line. When the driver sends a signal to the receiver circuit (high input impedance), voltage. To optimize net delay switching time and improve net wirability, it is desirable to minimize the reflected voltage on the net and restore the net to a DC value < _ MPUL (Most Positive Up Level). The receiver circuit shown in Fig. 2 contains a clamp circuit that is designed to respond to positive-going transients and limit the net voltage to < MPUL, which is 2.2 volts for the design considered. Transistors T1, T2, TR, diode DR and resistors R1, R2, RC and RS comprise the receiver circuit and transistor TC and resistor RBC comprise the active transient clamp.

Active Up-Level Receiver Clamp

Fig. 1 depicts a net including a driver circuit and a receiver circuit
interconnected by an unterminated length of transmission line. When the driver
sends a signal to the receiver circuit (high input impedance), voltage. To
optimize net delay switching time and improve net wirability, it is desirable to
minimize the reflected voltage on the net and restore the net to a DC value < _
MPUL (Most Positive Up Level). The receiver circuit shown in Fig. 2 contains a
clamp circuit that is designed to respond to positive-going transients and limit the
net voltage to < MPUL, which is 2.2 volts for the design considered. Transistors
T1, T2, TR, diode DR and resistors R1, R2, RC and RS comprise the receiver
circuit and transistor TC and resistor RBC comprise the active transient clamp.
Circuit operation is as follows: Consider the case when input A is down,
transistor T1 is off and output A is up such that TC is on and operating in the
inverted mode. Current will flow out of the collector of TC and is determined by
the following: I = -(bI+1) X IRBC for Vin = .6 V, RC = RBC = 8.0K and bI = 5, and
I = -.675 ma To minimize the clamp DC current flow when the receiver input is at
a down level, the TC emitter voltage supply (1.7 V) can be replaced by two
diodes as shown in Fig. 3. In this configuration, TC operates in the saturated
inverted mode however due to the high reverse impedance of the two diodes, the
collector current is minimized to: I = -...
